Hi s p s.

Sa 2 5 surface profile measurement.

Sa 2 5 or sa 2 1 2 sa 3 shot blasting grit blasting comparators iso8503 sa 2 1 2 sa2 5 sa 3 shot grit sand blasting surface comparator rubert elcometer tqc elcometer e125 1 grit blasting section profiles 25 60 100 150μm elcometer e125 2 shot blasting section profiles 25 40 70 100μm tqc ld2040 tqc ld2050 rubert 17. Coarse and extra coarse the surface profile measurement almost is a mandatory requirement by most coating specifications. We are a leading manufacturer of sa 2 5 surface roughness comparator we offer a wide range of sa 2 5 surface roughness comparator these two comparators item 017 for shot blasting 018 for grit blasting are specially designed to check the roughness of steel surfaces which have been blast cleaned to cleanliness grades sa 2 5 and sa 3 before painting. Rubert surface comparators 2 figure 5 the surface profile measurement principle figure 7 the replica tape kit showing the tapes on the left and the dial gauge on the right figure 8 the replica tape method.

Such is the nature of a blasted surface. Hopefully someone who is more knowledgeable about this will answer because i don t see how you can measure things that are covered by sa 2 5 like discoloration visible oil and greyness with a profilometer. For example on a panel blasted with a mixture of coarse and fine staurolite sands replica tape measurements ranged between 1 8 and 2 9 mils stylus instruments between 1 8 and 2 8. D7127 methods of measuring blast surface profile in addition astm d4417 11 provides an alternative way to measure the blast profile.

Amplitude surface profile amplitude is a measurement given in microns that shows the difference between the peaks and troughs in a metal surface produced by blast cleaning. Sa 2 5 or sa 2 1 2 sa 3 shot blasting grit blasting comparators iso8503 sa 2 1 2 sa2 5 sa 3 shot grit sand blasting surface comparator. Digital surface profile gauge to measure ra value on sand shot grit blasted surfaces. D7127 allows for the use of a stylus instrument that measures the rt which is the distance between the peak and trough of a blast pattern as well as the peak count in the blast section that is being assessed.

Figure 3 the keene tator surface comparator 1 with magnifier 3 and shot grit and sand discs. Two type of replica tapes is available in the market i e.
